將報表詳細信息導出到Excel文件時出錯

Question

我有一個窗體，其中生成報表並在datagridview中顯示，當用戶單擊「導出到Excel」時，datagridview中的數據將轉移到Excel文件中。 但即時通訊有問題：在GridView的第一行不會被保存在Excel文件 請幫助

在此先感謝

是即時通訊使用

 if (dgvCreditLimitTransaction.RowCount >= 1) 
     { 
      // creating Excel Application 
      Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();

代碼的修改代碼在下面，並註釋了評論。 IT是我的理解，你需要Excel電子表格中的第一列，但不是第一行。如果您需要進行任何調整，請留下評論，我會通過更新記錄。

//I changed i=2 to i = 1 to get first column header 
for (int i = 1; i <= dgvCreditLimitTransaction.ColumnCount; i++) 
{ 
    worksheet.Cells[1, i] = dgvCreditLimitTransaction.Columns[i - 1].HeaderText; 

    if (dgvCreditLimitTransaction.Columns[i - 1].HeaderText == "LC Number") 
    { 
     hdinvdate = i - 1; 
    } 
} 


//changed i = 0 to i = 1 to remove the first row, if you wish to keep the first row set i = 0 
for (int i = 0; i < dgvCreditLimitTransaction.RowCount; i++) 
{ 
    //change j = 1 to j = 0 so that you get 1st columns data 
    for (int j = 0; j < dgvCreditLimitTransaction.ColumnCount; j++) 
    { 
     if (dgvCreditLimitTransaction.Rows[i].Cells[j].Value != null) 
     { 
      if (j == hdinvdate) 
      { 

       DateTime tempinvdt = Convert.ToDateTime(dgvCreditLimitTransaction.Rows[i].Cells[j].Value); 

       worksheet.Cells[i + 2, j + 1] = tempinvdt.ToString("MM/dd/yyyy"); 

      } 
      else 
      { 
       worksheet.Cells[i + 2, j + 1] = dgvCreditLimitTransaction.Rows[i].Cells[j].Value.ToString(); 
      } 

     } 
    } 
} 
// Exit from the application 
//   app.Quit(); 
} 
else 
{ 
MessageBox.Show("Please select Data");
